The Synthesis and Evaluation of New α-Hydrogen Nitroxides for ‘Living’ Free Radical Polymerization

Three N-alkoxyamines were synthesized for use in nitroxide-mediated radical polymerization. Upon thermolysis, they generate new acyclic a-hydrogen nitroxides: one adamantyl substituted and two diol-containing nitroxides. The initiators were tested in polymerization reactions in direct comparison with the initiator derived from the nitroxide TIPNO.
